Interstate I-94 East from Ann Arbor, Michigan to downtown Detroit is a monotonous drive. Low-rise housing complexes, mall parking lots and the Detroit Metro airport pass you by on the mostly flat route, snaking its way towards the heart of the Motor City. But if there’s one weird landmark you’re not likely to miss along the way, it’s Detroit’s very own Uniroyal Giant Tire, rising more than 80 feet above the roadway.

This giant disk of premium rubber has been greeting Detroit-area commuters for more than 40 years. First built in 1964 as a monument for the World’s Fair in New York, the tire was originally a working Ferris wheel which could hold 96 riders. After the Fair’s conclusion the wheel was moved to its current home along the interstate. It’s been confusing and delighting motorists ever since, suddenly rising into view like a celestial hubcap sent from the heavens above.

It’s fitting that Detroit, a city that has long staked its reputation on the auto industry, would have such a landmark. But perhaps these days, with all the doom and gloom that’s been forecast in the state of Michigan, it’s become more a ghostly reminder of glory days past than a symbol of Detroit’s hopes for renewal. Still, for anyone who’s ever driven that flat road East towards Detroit, it’s a much needed symbol of whimsy and pride that never fails to make you smile.
